Each commercial customer is assigned a dedicated account manager. eCommerce customers can choose from next day, 2-day or 3-day national or international postal options.
Courier API can make your Whistl integration even more powerful. We have created a Shipping API that allows companies to integrate over 40 couriers to their eCommerce business. We developed this software to support synergy with our own warehouse management system. However, we quickly realised that our software would be valuable to eCommerce businesses. Our REST API integration allows you to access all the UK’s primary national and international transport and logistics services. Other carriers available for integration include; Royal Mail, Amazon Shipping, TNT, Yodel and many others.
Our industry-leading API provides consolidated Whistl Shipping management. Courier API was developed by developers for developers and allows eCommerce retailers to quickly and easily combine multiple shipping channels to your website at the click of a mouse. Generate labels with API requests centrally and our intelligent address formatting software means you can relax knowing that incorrect address inputs won’t delay your deliveries. All your customer and carrier data is fully encrypted using the latest technology, including world-beating AES-256 encryption.
